I see that you've tried some shading =D
I like the style and all, very reminiscent of your more wacked-out cartoons. In fact I'm pretty sure that that's more or less a one-word summery for your style and all. "Wacky". Pretty corny word...
Nice work, keep it up, etc. etc.
Might want to try shading with colours instead of hatching, just for an experiment.

I like your style. you manage to do a whole lot with very few lines. Simple without being simplistic if that makes sense. I think cross harching overly complicates your drawings though and would agree with the recomendation that you try shading with colors. Keep it up
